Be it known that we, LAFAYETTE BAUDEN- DIsTLE and J ULIEN A. DINGLEY,citizens of the United States of America,residin g at Denver, in thecounty of Arapahoe and State of Colorado, have invented certain new anduseful Improvements in Amalgamators; and we do declare the following` tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

Our invention relates to improvements in amalgamators and itconsists ofthe features, arrangements, and combinations hereinafter described andclaimed, all of which will be fully understood by reference to theaccompanying drawings, in which is illustrated an i.

embodiment thereof.

In the drawings, Figure 1 is a longitudinal Vertical section takenthrough the apparatus. Fig. 2 is a section taken on the line x x,Fig. 1. Fig. 3 is a section taken on the line y y, Fig. 1.

Similar reference-charactersindicating'corresponding part-s i11 theseviews, let the nnmeral 5 designate a suitable frame, in which isjournaled a shaft 6, having a fast pulley 7 at one extremity. To theextremities of the shaft, just within the journals, are made fast theheads 8 and 9, respectively. To these heads are applied an amalgamat-edplate 10, d

composed of a rectangular sheet of copper, which is bent around theheads, its longitudinal edges being overlapped, as shown at 10a. Thisplate is locked in place by metal straps 12,whose extremities areprovided with apertured flanges 13, secured by fastening-bolts 14. Asshown in the drawings, three of these straps are employed, one beingplaced at each extremit-y of the plate andthe other in the middle.

The heads 8 and 9 are provided with annular flanges Sa and 9,respectively, located a short distance from the extremities of the plate10. To these flanges are applied a cylindrical screen 15, which islocked in place eral No, 601,278. (No model.)

by longitudinal metal straps 1G, applied to the outer surface of thescreen and held in place by circular straps 17, surrounding the screenand secured by fastening-bolts passed through apertured fiangcs 17 a,formed on the extremities of the straps. The head S is closed betweenthe plate 10 and Jthe screen 15, as shown at 80, while between thefiange 8a and the collar 8d, surrounding the shaft, the head is open toreceive the pulp, which is fed into the machine from a chute or slnice1S,which discharges the material to be treated through the annularopening in the head. The collar 8d is connected with the annular fiangeSa by the Spider-arms S. The head 9 is open and is provided with anouter flange 9,which the plate 10 engages. The Itwo flanges 9 and 9c areconnected by narrow webs 9d, while the flange 9fL is connected wit-h thecollar 9;, by Spider-arms 9h.

The apparatns comprising the shaft, the heads, the am algamating-plate,and the screen are rotated by connecting the pulley on the'shaft with any suitable motor.

The pulp is fed into the cylindrical screen, which is of suitable meshto reject the coarser gangue, which is disoharged from the screenthrough the opposite head 9, while the finer material and thatcontaining the values passes through the screen to the amalgamated plate10, and as the apparatus is rotated the mineral particles are broughtinto contact with the said plate and saved,while the balance of thegangue is discharged from the machine between the flanges 9a and 9c ofthe head 9.

In cleaning up it is only necessary to nnfasten the straps 12 and removethe plate 10. The latter may then be spread out and the amalgam removedfrom its inner.surface,after which the plate is replaced and fastened asbefore.

This apparatus may be used in connection with a sluice, as inplacer-mining, or in connection with stamp-mills, or in any otherrelation where an amalgamator is desired.

Having thus described our invention,wl1at we claim is- In anamalgamator, the combination with a suitable frame, of the horizontalshaft journaled therein, the two open heads S and f) having collarssnrrounding and made fast to the shaft, said heads having ann ularflanges 8 and 9IL located at a suitable distance from their peripheries,the detachable amalgainatimg-plate applied to the periphei'ies of theheads and having its longitudinal eclges overlapped, fastening strapssnrronncling said plate and having flanges connected by suitablefastening devices, a detachable cylindrical screen Whose extremities areapplied to the fiang'es 8a and 9 of the heads S and 9, longitndinalstrips engag'ing` said screen on the outside,fastenin g-strapssnrronnding said
